In one of my several posts on this, probably to lkml, I mentioned that
all permutations of -no-acpi and -win2k-hack had been tried, none would
install with kvm (or xen). Using software qemu (-no-kvm) it works fine
for install, but won't run with kvm or xen.

I had another post indicating that a web forum reports that the problem
is that Intel hvm doesn't do real mode the same way as AMD, and that it
would properly work in AMD. I asked for feedback on that, haven't gotten
any to date.

Just as you say, the image is created and works. DragonFly BSD works,
and I've scheduled testing of the new FreeBSD-6.2 just released a few
days ago. Unfortunately Win98SE is a required test environment, and the
only place it seems to work is VMware, which indicates a software issue.
